7 Claims.

This invention relates to improvements in lunch boxes, such as areemployed with lunch kits. It is an object of this invention to provide alunch box having the box itself pressed or formed from a single blank ofsheet material and in which the exterior dimensions of the box arenogreater than that of boxes of this kind hereto-fore employed, and inwhich the bottle is partly-within the box, without, however, sacrificingany of the capacity of former lunch boxes, and in fact increasing thecapacity of such a box.

Another object of this invention is the provision of a box capable ofhaving use asv above and having regular lines and rounded corners,thereby aitording a box that can be readily and expeditiously cleaned,and materially advancing the sanitary conditions of these boxes, whenthey are used as lunch boxes,

A furtherobject of this invention is the provision of a lunch box or asimilar box, which is provided with vertical rounded corners and formedfrom a folded, stamped or died out blank, and which is relativelyheavily reinforced in-the stamping operation for maintaining the finalconfiguration thereof, and particularly the rounded vertical corners. f

It is another object of this invention to provide a lunchbox having abox proper,. a lid hingedly connected thereto and a so-calledvacuumbottle support so formed and co-operating with one another as tomaterially reduce thecost of the lunch box or lunch kit, whilematerially increasing the capacity of the box while holding the generaloutside dimensions of. the box substantially equal to those of lunchboxes or lunch kits as here-to-fore, known and used.

A still further object of the invention islthe provision of a lunch boxhaving the "so-called vacuum bottle support connected therewith, andwhich support may be arranged to increase the capacity of the box whenthe vacuum bottle is not utilized, and which support may be entirelydispensed with at the option of theuser without interfering with thegeneral construction of the box and cover, or disturbing the hinge connection of the box and cover, and which dispensing of the bottle supportfurther increases the capacity of the lunch box.

It is also a specific object of this invention to provide-a novel,inexpensive, yet highly efficient catch for securing the cover in aclosed position on the box, and which catch. will operate even thoughthe box has been mistreated to. a point beyond which catcheshere-to-fore known and used would be inoperative. l l

the shoulder 44 and therefore parallel with the front when in upstandingposition and thereby providing a flange 45 behind the cover bead 23. Theends of the front portion 33a of the blank are provided with a pluralityof outwardly projecting ribs 46 which extend longitudinally of the fronta distance somewhat greater than the periphery of the rounded cornercuts 38 of the bottom, these ribs having their outer ends open and innerends closed and acting as corrugajtions for stiffening the ends of theportion 33a Specifically, and in general, the lunch box of thisinvention comprises the box proper, indicated in general by thereference character 2|], to which is hingedly secured the top or cover2|. The cover 2| is a drawn shell having a transverse cross section, asindicated inFig. 3, and, as will be seen from Fig. 3, has its lonitudinal corners rounded, providing a fiat top portion 22. In plan, thecross section follows generally the outline of the plan of the box, asillustrated in Fig. 4, and with its vertical corners correspondinglyrounded. The lower edge of the top or cover 2| is turned onitself toprovide a reinforcing bead 23.. The fiat portion 22 of the cover 2| isutilized for attaching thereto a carrying handle, and this handle maytake any desirable form. As specifically shown in the drawings, the saidfiat portion 22 is provided with spaced pairs of piercings 214 and 25 toprovide sockets. each pair are in axial alignment, and respectivelyreceive similar bail handles 26 and 21, which together constitute thecarrying handle for the lunch box or kit.

The box proper 28 is formed from a metal blank 28, shown in extendedplan in Fig. 15. This blank i somewhat similar to the blank illustratedin United States Patent No. 1,912,915, issued to Corresponding socketsof when bent or formed around the cut corners 38.

The back portion of the blank is of the same general dimensions as thefront portion 33a,

' and is provided with dotted lines 41, 48 and 49,

respectively corresponding to dotted lines 4|, 42 and43 of the frontportion, and are for the same purpose as said dotted end bend lines offront portion 33a. As will be seen, however, the dotted or bend line 49does not extend for the entire length of the back portion 35, but onlyinwardly of the ends thereof to the tops of the elongated apertures and5|. These apertures 58 and 5|, however, have their lower ends connectedby a dotted or bend line 52 which supplies the remainder of the bendline 49. The purpose for this'is to provide a space for the hingeextension 53 of the top 2|, as illustrated in Fig. 3. In other words, ashoulder similar to 44 is provided throughout the length of the backportion with the portion between the back shoulder portions lowered toaccommodate the hinge bead of the top. Beyond the elongated perforations50 and 5|,the back portion 35 is provided with a pair Louis M. Piker onJune 6, 1933, but is an improvement thereover in several particulars, aswill be pointed out later. The sheet metal blank 28 is providedcentrally thereof with-a portion 29 constituting the bottom of the boxand outlined or defined by dotted lines 30, 3|, 32 and 33, whichrespectively define th lower ends of the front 33a, right hand end 34,back 35 and left hand end 36. Extendingfrom the dotted lines 3| and 33,or the bottoms of the ends 34 and 33, is a narrow strip or neck,represented at its ends by cut lines 31. The bottom portion 29 has eachof its corners similarly rounded, as at 38, and these rounded cornersoutline or define the roundness of the corner in the bent up box. Aswill be seen, the cut portion of these rounded corners extends from thepoints 39 at the ends of the longitudinal dotted or bend lines'30 and 32to the points 40 at the inner ends of the neck or stripcut lines 31.

The front portion 330. of the box is' of greater length than the bottomportion 29, as defined by dotted or bend lines 3| and 33. The outer endsof the front portion 33a is provided with dotted lines 4|, 42 and 43,which-are bend lines, and on which the blank is bent or folded asfollows: the portion of the blank between the dotted or bend line 4| andthe outer edge of the blank is folded onto the portion between the bendlines 4|l and 42 to provide a reinforced upper-edge for the front of thebox, the portion between the bend lines 43 and 42 is bent to project atright angles to the remainder of the'front, and willtherefore beparallel with the box bottom 29 when in assembled position to providethe shoulder 44 on which rests the cover bead- 23, as seen for examplein Fig. 3, and the remainingportion between bend lines 4| and '42 isbent at right'angles to of inwardly projecting lugs 54 and 55, which, aswill later be made clear, act as hinge pin stops.

The box'end portions 34 and 36 are identical in construction, and it isdeemed sufficient if but one of them be described in detail for theother, end portion 34 for example. The end portion 34, when in finallybent up position, is slightlynar rower than the width of the bottomportion 29, asdefined by the dotted or bend lines 30 and 32.

p The end portion 34 has extending longitudinally thereof, and ascontinuations of the neck or strip cut lines 31., dotted or bend lines51 and 58. Outwardlyof the bend lines 51 and 58 are bend lines 59 and68, which bend lines 59 and 6B are spaced from the bend lines 51 and 58a distance substantially equal to the length of the neck or strip cutlines 31. Outwardly of the bend lines 59 and 68, the end portion 34 hasflaps BI and 62, which, for. clearance in assembly, have their upper andlower ends suitably cut away to the points of the bend lines 59 and 60.The material between bend lines '51 and 59 and 58 and 60 is adapted toextend at right angles to the body of the end 34 and form shoulders,such as 33, illustrated in Fig. '1, and which shoulders extendvertically of the box in alignment with the neck or strip ends 31. Whenthe box is in finally assembled position, the shoulders 63 close theouter, open ends of the ribs 43, as clearly illustrated in Fig. '7. Theflap portions 6| and 62 are bent against the inner surface of therounded corners of the ends of the front and back portions, and theseflap portions are each provided with one or more ribs I04. Beyond theupper ends of the flaps 6| and 52 is a tongue 64 having a width equal tothe space between dotted or bend lines 51 and 58. This tongue 54 isprovided longitudinally thereof with dotted lines 65, 66 and 61, whichcorrespond to the dotted lines 4|, 42 and 43 of the front portion 33a,and are for the same purpose namely for providing a cover shoulder 44and flange 45. It

aeears will be appreciated, however, that. the material between dotted.lines 65 and 61. is greater than that between dotted lines 42 and 43 inorder to keep the peripheral flange at the ends of the front and backportions in alignment with the peripheral flange of the side, and toprovide for the offset in the ends, as required by the neck or strip cutlines 31.. ,Within the body of the end portion 34, there isprovidedseveral similar piercings 58 which are bent to form air openingsor louvres 69, see Fig. 8, for the box.

In erecting the blank, the end. portions 34 are first bent upwardly fromthe position. shown in Fig. 15, causing the shoulder 63 of said endportions to align with the neck or strip cuts 31-. The front and backportions 33a and 35. are then bent upwardly, and the ends of saidportions formed around. the bottom corner cuts 38 to dispose theopenends of the ribs 46 into substantial contact with the shoulders 36,and thereby close the inner ends of said ribs. With the parts in thisposition, the end flaps BI and 62 are pressed against the inner face ofthecorners, all as i1- lustrated in Fig. 7.

It should be noted that the ribs I04 in the end flaps BI and 62 arelocatedbelow the dotted or bend line 61, the samedistance that theuppermost rib '46 of the front and back portions 33a and 35 is locatedbelow the dotted or bend lines 43 and 49. These flap ribs I04 areadapted to enter and nest with the said front and back up-, permost ribs46 for the purpose of vertically aligning the overlapped flaps and endsof the front and back portions. It will be understood that the flaps maybe provided with more than one rib I04 if desired, and infact. may havethe same number of ribs as there areribs 45.

The flaps and contacting ends of the front and back portions 33a and 35are then secured-to one another as by a plurality of spot welds 10, seeFig. 8, or this connection may be made by seaming or any other knownmethod of combining metal parts. By this construction, the lower edgesof the front and back portions of the blank, namely, the portion thereofextending beyond the points 39, are contacting the edge of the bottomportion 29 along the out line 38. In order toefe fectively close thisjoint, the bottom portion 39 is provided with an upstanding orembossedrib. This rib takes the form of an X shape, shown in dotted or bendlines ll in Fig. 1.5. It will be noted that the ends of these arms flareto meet the points 39 and 40 of the bottom round corner cuts and toprovide a closed corner where the sides and bottom meet. I

As was noted above, the top 2| is provided with an extension to form thehinge extensions53, the lower end of this hinge extension being turnedon itself, as at 12 in Fig. 3. to receive the hinge pin or pins as willlater be described. The hinge pin bead I2 is or may be substantiallyidentical with the bead 23 at the lower ends of the cover side and endwalls, and when made as above described, the back of the lunch box orkit seems to have the central portion of the beaddropped.

' The foregoing box blank and cover,'while specifically illustrated inthe drawings, and here-tofore described, as forming a lunch box, it willbe appreciated that with a few changes it may be adapted to variousother uses, such as an individual metal file box, storage'case, and infact any box, receptacle, case or the like having walls connected to oneanother around. rounded corners.

, Continuing: with the specific disclosure of the (I respectively on thepins TI and I8.

lunch box, and with reference to Figs. 3, 4 and 5,, there is provided a:so-called vacuum bottle carrier. This bottle carrier-is formed from asingle length of wire substantially V-shaped, as clearly illustrated inFig. 4 when viewed in plan. As shown in this Fig. 4 the bottle carrierhas a short angular arm 13 and a relatively longer angular arm 14. Thesearms are joined at their apex by a straight connecting piece 15 which ishook shaped, as shown most clearly at 16 in Fig. 5. The other ends ofthe arms 13 and 14 are respectively turned or extended toward oneanother toprovide hinge pins 11 and 18 which enter from opposite ends ofthe cover hinge bead 12. In observing the carrier arms 13 and 14 fromone or the otherends. of thebox, said arms are arcuately bent, as at 19in Fig. 3, to form a cradle for the so-calledvacuum bottle 80, indicatedin phantom lines in Fig.3. The hook I6 and connecting piece 15 at theapex of the botthe carrier is received in an inwardly disposed notchor-seat 8| which is formed in the box flange 45 at a point toone side ofthe longitudinal center thereof, since in the form illustrated, a latchmechanism, to be described later, occupies the longitudinal center ofthe box. It will be appreciated that if the latch or other lock meanswere provided off center, the hook and connecting piece 16 and 15 wouldbe located at the longitudinal. centerof the box, and the carrier arms13 and 14 would then probably be of equal length and equal divergence toone another.

The insertion of the hinge pins H and 18 into the top hinge bead islimited by lugs 83, and 84,

are so related tothe pins and their respective bottle carrierarms l3 and14 as to bring the bend 85, see Fig. 7, between the hinge pin and itsarm, directly against the inward lugs 54 and 55. of these connections isparticularly illustrated in Fig. 7. The natural spring in the bottlecarrier.

arms 13 and 14', and the co-operation of their hinge lugs 83 and 84 andarm bends 85 with the lugs 54 and 55, tend to maintain a frictionalengagement between the lugs 83 and 84 and the cover hinge bead 12, sothat when there is no bottle on the carrier the movement of the covercarries with it the carrier, .until the carrier is substantiallyvertically of the box. Furthermore, with this type of construction, thelugs 83 and 84 limit the movement of the. hingepins toward one another,while the bends 85 at the ends of the arms Hand 14, contacting with thelugs 54 and 55, prevent the outward movement of these pins. Thisconstruction carries with it another advantage, in. that, should theuser desire not, at any time, to use and to dispense with the bottlecarrier, the wire may be nipped just at the outer edge of the lugs 54and 55, without in any wise endangering the hinge connection of thecover with the box, since the hinge pins will be retained in position inexactly the same manner as above described.

Since the forward support, namely, the connecting piece 15 and hook 16of the bottle carrier, is located behind the wall of the cover 2|, thesaid bottle support, if it were desired not to use the bottle, could bepositioned as shown in dotted lines at 82 in Fig. 3, thereby increasingthe capacity of the lunch box to the extent shown by the space betweenthe solid and dotted line positions. of the bottle carrier in Fig. 3,and at the same time keep the upper lever of the contents of the boxbelow the top thereof.

In Figs. 12, 13 and 14 a slightmodification is These lugs One 3illustrated, in that use isthere made of a separate hinge pin and bottlecarriezfland with the hinge pin 81 the full distance between the lugs 54and 55 and' is retained in position against displacement by these lugs.Immediately below the hinge, the back 88 of the box, corresponding tothe portion 35 of the blank, is provided with piercings to form sockets89 and 90 adapted to receive hinge-or pivot arms 9| and 92, respectivelyformed at the inner end of bottle carrierarms I3 and I4. With thisconstruction, if it is desired to dispense'with the bottle carrier, itis only necessary to outwardly spring the arms I3 and 14', and therebydisengage it from the box. With' this construction also, if it isdesired not to use the so-called "vacuum bottle, and thereby increasethe capacity of the box, it may be swung upward into the cover, asshown'in dotted. lines at 82 in Fig. 12.- a

From the above, it will be appreciatedthat the capacity of the lunch boxis greater than lunch boxes here-to-fore employed, even though thegeneral external dimensions are substantially the same, and that thecapacity of the lunch box can be increased without in any wisederanging' the parts thereof, or can be further increased by dispensingwith the bottle carrier.

In order to hold the cover in a closed position, use is made of a novellatch mechanism. For this purpose, the front portion 33a of the boxblank is provided with a pair of apertures 93 and 94, through the formerof which extends a rivet 95'for securing the lower end I05 of a fiatsteel spring strip 96, see Figs. 9 and 17. 'A button 91 is secured tothelatch for the operation of said latch spring. The latch 96 is ofconsiderable width, as shown most clearly in Figs. 10, 11 and 17, and isformed to lie closely against the inner surface of the front wall of thebox, and in order to insure this, the lower end I05 of the latch is benttoward the box front so that when said lower end is secured by the rivet95, the latch is biased toward the box front. Intermediate its ends, thelatch is bent outwardly, as at 09, to pass around the cover shoulder andbox flange 44' and 45, and-rest against the inner surface of the flange45; The upper end of the latch 96 is bent outwardly and downwardly tothe body portion, as'shown at I00, and passes through an elongatedaperture IOI in the front wall of the cover 2|. The outward and downwardangle of the locking fingers I00 is such that pressure thereon from thecover 2| will cause the latch to move inward andthen snap through thecover aperture 'IOI. It will readily be appreciated that inwardpressure, to the right as seen in Fig. 9, on the buttonflI will flex thespring steel latch 96 sufficiently to withdraw the locking finger 'I 00from the aperture IIlI, so that the cover may be actuated about itshinge connection. It should be noted that this latch is highlyefiicient, since the latch need only have a small part of its fiatlocking finger I00 within the aperture IOI to hold the cover inposition; this position is illustrated in dotted lines at I02 in Fig.11. If desired, the finger I00 may be provided with an aperture I03 forthe reception of a suitable lock pintle to prevent undesirable openingof the cover.

The modification shown in Figs. 18 and 19 utilizes no front end supportfor the bottle carrier while still having the bottle carrier positionwithin the box as shown in the other drawings and above described. Thisbottle carrier is formed from a single length of wire and is asubstantially rectangular frame instead of a V- shaped frame, andcomprises a pair of arms I98 and IM having their one ends bent towardone another'to form hinge pins I08 and I09. These hinge pins I08 andI09, similar to hinge pins I7 and I8, simultaneously hingedly mount thecarrier on thebox and connect the cover to the box. It will beunderstood that, if desired, the cover could be hingedly connected tothe box by aseparate hinge pm as in Fig. 12, for example. The arms I06and I01 may be curved, as at II to form a cradle, contacting with theexterior of the bottle, and the arms have their otherends joined by thebar section III, Between the cradlesIIIl of the arms proper I06 and I01and their respective hinge pins I08 and I09 is a vertical portion II2,which lies against the inner surface of the back the the box, as seenclearly in Fig. 19. This vertical portion I I2 of the arms'maintain themin a shelf like, horizontal position, on which rests the bottle 80. Bybending the arms relative to their vertical portions II2 so as to tiltupwardly a very slight amount, the bottle may, in effect, be clampedbetween them and thenlto the top of the cover, thereby eliminating anyrattle or movement of the bottle within the box and cover after thecover is secured in closed position. v

The bottle support illustrated in Figs. 18 and 19 and just described, isprimarily intended for use with round bottles, while in Fig. 20v is mus.trated a modification in the shape of the carrier for supporting asubstantially square bottle. The only change necessary is thatthe armsI06 and IN, instead of having the cradles I I0, may be formedsubstantially straight as shown at H3 with their ends upwardly curved asat H4 an joined by a bar section'such as I I1.

With each of the constructions illustrated and described, it will benoted that the bottle carrier is hingedly mounted on the box and isprovided with means which co-operate with the box for maintaining thecarrier in proper position. In the forms illustrated in Figs. 3 and 12,these cooperating means is the hooked ends IS on .the bottle carrier andthe front wall of the box, While in the form illustrated in Fig. 19,these co-operating means is the vertical portion N2 of; the bottlecarrier and the back wall of the box.

From the foregoing, it will be readily appraciated that the constructionillustrated in the drawings, and particularly described, will meet allof the objects initially set forth, as well as other objects notspecifically mentioned.
